查询词典 silver-gray

The results show that sulfite ion increases with pH value and concentration of sodium sulfite, which results in the increase of solubility of silver chloride. In the circular leaching solution, the solubility of silver chloride becomes lower with the increase of concentration of chloride ion.

结果表明：pH值的增大和亚硫酸钠浓度的提高，使与银配位的亚硫酸根离子增多，从而氯化银的溶解度明显提高；在亚硫酸钠循环浸出氯化银的过程中，溶液中不断积累的氯离子导致浸银效果逐渐变差。

In this paper, the mechanism of leaching of silver chloride by ammonia and the influences of concentration of ammonia, pH value of the solution and concentration of chlorine ion on the solubility of silver were studied.

摘 要：作者利用配合物化学理论，对氯化银在氨水中的溶解度进行一系列计算，结果表明氨水浸出氯化银时，氨浓度、pH值、氯离子浓度对氯化银溶解度都有影响。

In this dissertation, sensitization and its mechanism by some well-known stabilizers, especially 5-methyl-7-hydroxyl-tetraazaindene in silver chloride emulsion have been systematically studied It is found that sensitization by stabilizer is obvious in whatever unsensitized or sulfur-sensitized silver chloride emulsion, as well as fog-inhibition.

本论文研究了一些常用的有机稳定剂特别是四氮杂茚在氯化银乳剂中的增感作用及系统地研究其增感作用机理。

In industrial production, the solution can circularly leach silver chloride 11 times when the concentration of sodium sulfite is 2mol/L and the concentration of silver ion is 30g/L after every leaching process.

结合工业生产，确定了亚硫酸钠浓度为2mol/L，控制每次浸出液中银的浓度为30g/L时，亚硫酸钠溶液可以循环浸出氯化银11次。

They immersed a lead object first in copper acetate (a compound made by letting vinegar corrode copper), and then in a silver solution created by dissolving silver chloride in dilute ammonia (which ancient chemists made from urine).

它们首先把铅制品浸没在醋酸铜（通过醋酸腐蚀铜而制得的化合物）中，然后放在银溶液中，银溶液是通过把氯化银溶解在稀释的氨水中而制得的。
